RecruitingWearable Sensors to Detect Atypical Muscle Activation in Young InfantsThe purpose of this study is to see if wearable sensor technology can be used to evaluate muscle activity and/or identify atypical muscle tone in infants up to 48 weeks postmenstrual age (8 weeks corrected age). These sensors are placed on the surface of the skin and record data about a child's body movements and muscle activity.
